Prevent serious damage

Bar Flex and Cem Flex

Understanding lintel failure

A lintel is the beam above a window, door, or other opening, supporting the weight of the wall above. In older constructions, timber window frames sometimes acted as structural lintels. When these frames are replaced without installing a proper lintel, serious cracking or movement can occur.

Common causes of lintel failure

Age and material fatigue
Over time, stone, timber, or even concrete lintels can weaken or degrade.

Modern window replacements
Removing old frames that supported part of the structure without replacing them with a lintel.

Poor original construction
Inadequate materials or techniques used when the building was originally constructed.

Why immediate action is important
Failing lintels can compromise the entire structural stability above an opening. Early detection and repair can prevent more extensive and costly damage to your property.

How we repair lintel failures
